"It was wonderful working with Farhan. I must say that of course, I knew his work. I had watched his films. But I was very happy I watched 'Bhaag Milkha Bhaag' after our shoot was over," the 34-year-old said here Monday at the first look launch of "Shaadi Ke Side Effects."
"I couldn't have gone back on the sets after having watched that film. I couldn't have performed with him after that film," she added.
Farhan also praised Vidya for knowing well what is required of her which in turn helped him perform better.
"Honestly, as an actor or as a director when you go on set you want to work with people who are good at what they do, who are hungry about their work, who are also willing to listen and learn along with you because everyone is learning on the job," Farhan said.
"On that level, she is a very strong performer, she has a great understanding of what she needs to do in the film. When you are working with somebody like that, you take a lot from them and that helps you to perform well because you are constantly being challenged," he added.
